Filtered Connector Express™
Configure a filtered connector for the EMI protection you need.
And get delivery fast. Ideal for prototypes or production quantities.
Modern electronic systems demand high-performance EMI filtering without sacrificing flexibility, reliability, or speed. Custom EMI-filtered connectors often require tradeoffs between performance, customization options, and lead time.
Our line of configurable connectors allows you to quickly and easily specify features such as package and filter values for each pin. We can then create that filtered connector to your specs more than twice as fast as the industry average.

Configure your connector today!
Spectrum Control’s solution cuts lead times up to 50% with fast, web-based configuration. It enables efficient integration of high-performance EMI filtering across a wide range of mechanical and electrical options for new designs and retrofits, preserving performance, improving compliance, and reducing overall program risk.

Filtered D-Sub Connectors

D-sub connectors are widely used and key for EMI control. As complexity and timelines tighten, engineers need faster, flexible filtering.
Filtered D38999 Connectors

EMI-filtered circular connectors are vital for military and aerospace systems. As density and timelines tighten, engineers need faster integration without delays.
High-Performance, Configurable EMI Filtering, Delivered Faster
Spectrum Control eliminates these constraints with an expedited, configurable approach to connector-based EMI filtering. Through solutions like the Configurable Connector Express™ you can design application-specific filtering directly into the connector, stopping interference at the point of entry, where it is most effective and space-efficient. In fact, a single filtered circular connector can replace up to 128 discrete filters, significantly reducing system complexity.
Using intuitive configuration tools and decades of EMI/EMC expertise, Spectrum Control enables selectively loaded, custom connectors to be designed and ordered with ease, cutting traditional lead times by up to 50% and delivering fully customized circular connectors in as little as 12 weeks, with no NRE. The result is faster prototyping, streamlined integration, and high-performance EMI protection tailored to your exact requirements.
